This version from the Space Invaders series is absolutely the most ironic, colorful, and funny, with graphics and sound totally remade, but keeping the same game scheme. After having inserted our coin, you choose the character you want to play with: each of them has got its own spaceship and an extra weapon in addiction to the default one. It's possible to play in two persons at the same time.
To drive away UFO and save Planet Earth we have to defeat invaders during 5 rounds divided in several stages (32 in total), inside of which we'll find a bonus stage and we'll have to fight with the end of round boss.
First round starts with the already seen space invasion by aliens in 4 rows, graphics are the same as in 1978, to protect ourselves we have 4 barriers, but, after a few seconds... The transformation! The monochromatic space invaders are now funny and colorful aliens! But, careful, never judge by appearances: they are better trained than their predecessors! In certain points of the game it will be nearly impossible to avoid the so many shots coming down; it's not an easy way to arrive to the last round!

At the bottom of the screen, under our hero, there's a bar indicating the loading state of the additional weapon. Keep pushed fire button and leave it when the indicator shows the maximum load and you'll have a single shot with devastating effects for the unlucky aliens.
Characters to drive are quite weird: we can find a dog in a stood shooting bones, a modern version of the first Space Invaders tank wearing shoes, a rock, a robot shaped as a Japanese amulet (with an additional weapon extremely powerful), and the space ship Silver-Hawk from Darius.
At the end of first round (Space-Carrier) we'll have to face a huge robot trying to hit us with a burst of bullets and with big metal spheres, and, when it will start running it's because it's going to call three rows of invaders to help. Entering the following round (Gourmet Star) the boss is the huge ship 106780 Yamato, a terrific battleship with a ramshackle look, equipped with laser cannon, driven by a prawn and a big squid and the huge battleship Fossil A from Darius. In third round (Summer-Star) the boss is a lobster-girl designed in manga style who lives on a small island with hanging out washing. Fourth round is the Ghost-Star with a space ghost to destroy.

Passed this round with a horror atmosphere we arrive to the fifth and last round (Mother-Star) where we face an enormous robot looking like the first Space Invaders one, driven by King UFO. The robot is equipped with laser cannons, extensible arms, and from the eyes shoots pieces of Tetris wall. Once defeated it, King UFO will escape with all its space creatures, giving in with the Earth invasion. Wondering if there will be a sequel!
The features taken from the old Space Invaders are: spaceship at the top of the screen flying from left to right (Mother-ship) and the fact that if aliens come down under the barriers there will be an invasion and we'll lose one life.
As in Super Space Invaders 91 sometimes from the Mother-ship an arm will fall down, and, picked it up, it can be used against enemies. It will happen to pick up a bowling ball, and, by throwing it away, it will sweep away all enemies on its way. Other weapons are: a bullet loader allowing to shoot in rapid session and a bomb that will make exploding everything inside its ray. Another object that we can pick up is a watch that will stop time for a few seconds. Hit Mother-ship will fall over and, if shot again, will explode; if an alien will happen to be near the explosion will we destroyed as well.

Among the weirdest situations in this game I mark out Summer star where aliens arrive by sea in a life belt, then they go to the beach, sheltering themselves from our shots in holes in the sand, behind palms or small heaps of sand. In fourth round, Ghost Star, boss brings back to life the 78's Space Invaders, on which we can see the scanlines!
The variety of aliens in this game is impressive, together with the many innovations; probably the most conservative Space Invaders fans won't like this version, but certainly all the other will appreciate it, on condition that they are keen on these kind of games.
